CARDIFF, Wales (AP)—Heavyweight fighter Dereck Chisora lost his British boxing license on Wednesday for brawling with former WBA champion David Haye at a news conference in Germany following his failed WBC title challenge against Vitali Klitschko.

Chisora faced the British Boxing Board of Control in Cardiff to explain why he fought with Haye after losing on points to Klitschko on Feb. 18 in Munich. He also slapped Klitschko at the weigh-in and spat water at his opponent’s brother, Wladimir, before the fight.

“Dereck Chisora, by his own admission, did not behave in a manner consistent of a professional boxer and let down not only himself and his family, but also all of those license-holders who behave in a professional and disciplined manner,” BBBC secretary Robert Smith said of the indefinite ban.

“The stewards of the British Boxing Board of Control want to make it absolutely clear that such behaviour by any license-holder will not be tolerated.”

Chisora has 14 days to appeal the decision and his promoter Frank Warren said that would come under consideration.

The BBBC also said that it didn’t have any power to sanction Haye as he isn’t a license-holder.

“However, if he should apply for a license with the British Boxing Board of Control, the part he played in the disgraceful scenes that occurred in the post-contest press conference will be considered and taken into account by the stewards before any decision is made,” Smith said.

Chisora made a cryptic comment after the hearing.

“Three letters—MGM, here I come,” Chisora said in an apparent reference to the MGM Grand in Las Vegas.

The Nevada State Athletic Commission would have to decide whether to grant Chisora a license if he wanted to fight there.

Chisora was suspended indefinitely by the WBC on Feb. 28, taking him off its rankings and plans to impose a “serious fine.” The amount will be determined after a hearing.

The WBC described Chisora’s actions as “one of the worst behaviors ever by a professional boxer,” and said he must seek treatment for anger management before his suspension could be overturned.

Chisora, who issued a statement a week after the fight to “wholeheartedly” apologize for the brawl, was questioned by Munich police for several hours but was released without charge. Haye left Germany before police could talk to him.
